I suppose some marketing weasel or corporate lawyer could argue that because over 50% of the pack it meaty, the overall pack is meaty, compared to another pack that had 4 x Cheese and Onion, 4 x Ready Salted, 4 x Salt and Vinegar, 4 x Barbecue Sauce and 6 x Prawn Cocktail

I know cheese used to be made from rennet (cows stomach) and therefore not suitable for vegetarians, although these days vegetarian suitable rennet is used.

At the same time as reading 'not suitable for vegetarians' in the cheese and onion crisps, the meaty ones were deemed suitable for them :-) It's all down to the legal definiations of flavour and flavoured.

The large bag in the photo contains 22 standard sized packets. With standard sized crisps/chips.

Ah I see. Well I know Lays (AKA Walkers) used to promote that their bags were more "full" than their competitors. But all they did was made the bag smaller so it seemed like it was more full. It was still only 1 pound of chips. Maybe they are doing the same over there by declaring them as "meaty" rather than just "more full"???
